What owners report

Owners of this 2020 Defender most often describe daytime running light and headlight LED failures, and some report dealers quoting full headlight replacement at high cost. Cracked windshields with no clear impact form the second theme, followed by sudden engine or vehicle shutdowns, steering that locks or acts on its own, and hybrid DC-DC converter failures. Mileage is missing from the structured data for most of these reports, and the text of some lighting and windshield complaints places failures after the factory warranty or at low mileage.

  1. Exterior lighting

    Daytime running light or headlight LED failure

    • 14 complaints (24%)
    • median 40,000 mi at 6.0 yrs old (1 states mileage, few)
    • filed 2024–2026

    Owners describe the daytime running light or halo ring going dark, with the LED module or headlight assembly failing, sometimes on both sides. Some owners say the dealer offered only a full headlight assembly replacement at high cost, and others say warranty coverage was refused. A complaint attributes the failure to poor cooling of the LED module. Mileage is missing from the structured data for these complaints, and the text often describes failures that come after the factory warranty has expired.

    What to check: Check that both daytime running lights and the halo ring light up when the car is switched on, and ask whether any headlight assembly has been replaced. Ask the seller for records showing the warranty status of any lighting repair, since some complaints describe refused coverage.

    2 excerpts from owner complaints in NHTSA records

    “Our 2020 Defender's halo light on the driver's side has become inoperable & poses a safety hazard. After researching this issue, it appears that this has been reported widely online. This malfunctioning halo light renders overall lighting very dim at night, creating a safety hazard for my vehicle & other drivers on the road. …”

    NHTSA complaint #11759119, filed 2026-08

    “The daytime running lights which also dim the overall lights at night, also known as the halo LED light continues to malfuction. I bought this car (2) years ago and I'm now on the second set up LED running lights. There are numerous other reports of this malfunctioning across owners. multiple online forums. this overall poses a large saftey hazard as the light is very dim at night from it not running, also including the daytime light casuing saftey issues for other cars.”

    NHTSA complaint #11667939, filed 2025-06
  2. Visibility (wipers, defrost, mirrors)

    Windshield cracks with no clear impact

    • 8 complaints (14%)
    • median 7,434 mi at 1.8 yrs old (1 states mileage, few)
    • 1 mention a crash, fire or injury
    • filed 2021–2026

    Owners describe windshields cracking with no apparent strike or with only a small pebble, sometimes starting at the bottom edge or the A-pillar area. Some owners say the windshield cracked again after replacement, and a complaint says the dealer would not replace it under warranty. Owners say similar windshield reports appear widely in online owner forums. Mileage is missing from the structured data for these complaints, and some describe cracks at low mileage or shortly after installation.

    What to check: Check the windshield for small chips or cracks, including near the bottom edge and the A-pillar, and ask whether it has been replaced before. Ask the seller for any windshield replacement invoices and whether a warranty claim was made.

    2 excerpts from owner complaints in NHTSA records

    “We have had our vehicle for 3 years and had to replace our windshield twice from random cracks starting from the exterior windshield where it meets the body of the care. It has happened on its own, twice, which impact from any object. The cost of the windshield, as installed is over $2000 each time, and it is repeated occurrence with owners.”

    NHTSA complaint #11717917, filed 2026-02

    “2 windshields cracked within a 2 month period. Second windshield cracked about 45 days after installation with no evidence of any impact causing it. One morning I came out to my vehicle and there was a 6-8 inch crack starting at the bottom of the windshield. Have driven the same roads for 30 years and have never had issues with windshields and now 2 in a couple of months.”

    NHTSA complaint #11547487, filed 2023-09
  3. Engine

    Sudden engine or vehicle shutdown while driving

    • 7 complaints (12%)
    • median 48,000 mi at 7.0 yrs old (1 states mileage, few)
    • filed 2022–2026

    Owners describe the engine faltering, stalling, or shutting off while driving or at stop lights, sometimes with warning lights or messages on the dash. In some complaints the engine would not restart after it shut off, and a stop-start system left the car in Park in traffic. Some complaints describe a sudden loss of all power after warning lights came on, and others describe the car shutting down on an icy road. The only mileage stated in this group is 1,297 miles, and the events are described at highway speed, at stop lights, and on icy roads.

    Recall 21V4240002 related service bulletins

    What to check: Ask whether any warning lights or messages were logged before the engine shut off, and whether the powertrain control recall was checked. On a test drive, check that the engine restarts normally after a stop and that no warning lights appear.

    2 excerpts from owner complaints in NHTSA records

    “While I was driving, the vehicle shut down unexpectedly. I was sliding sideways across the road on ice on the side of a cliff and luckily was able to stop the vehicle before going off the side of the mountain. I had to entirely restart the vehicle to begin driving again.”

    NHTSA complaint #11733249, filed 2026-04

    “I was driving at a speed of 66 miles when the engine died, the cluster showed a red triangle and showed an alarm setting message. Steering wheel vibrate and I could not moved. This event last around 3 seconds and the alarm disappeared and the engine came back.”

    NHTSA complaint #11454234, filed 2022-02
  4. Steering

    Steering locks or lane-keep steering acts on its own

    • 7 complaints (12%)
    • median 1,900 mi at 1.0 yrs old (3 state mileage, few)
    • 1 mention a crash, fire or injury
    • filed 2020–2026

    Owners describe the steering wheel locking so the car cannot be driven, and power steering disabled or locked for a short period. A complaint ties the power steering lock to a recent software update. Other owners describe lane-keep steering moving the car on its own, including when the feature had been turned off. According to a complaint, the dealer said there was no remedy for the lane feature. Where mileage is stated it falls between 800 and 5,000 miles, and the lane-keep event is described on a straight highway.

    What to check: Ask whether any software update was installed and whether the dealer has a fix for the lane-keep feature. On a test drive, check that the steering wheel moves freely and that lane keeping stays off when it has been switched off.

    2 excerpts from owner complaints in NHTSA records

    “Total brake and steering loss at 60mph ..I can send you the screen shots tomorrow/ november 23rd (prom the photos taken on my son's phone of the dashboard notice...plus a virtual ghost-like abrupt take over of lane assistance despite my having turned that off!”

    NHTSA complaint #11375851, filed 2020-11, 1,900 miles

    “This happenedtwice after the most recent update(os 3.0). When i turned on my vehicle and engaged drive, power steering was disabled and/or locked. Im not sure which it was, but steering the vehicle was not possible, for several seconds, until it resolved itself.”

    NHTSA complaint #11446777, filed 2022-01
  5. Electrical system

    Hybrid DC-DC converter failure and power shutdown

    • 5 complaints (9%)
    • median 48,000 mi at 7.0 yrs old (1 states mileage, few)
    • filed 2026

    Owners describe the 48-volt DC-DC converter failing, with the vehicle losing power or shutting down while driving, and a high-voltage shutdown warning appearing after a check engine light. Some complaints describe a total loss of power linked to a converter microchip failure, and others describe a fire concern from the failed converter. Some owners say the replacement part was backordered for a long time. The only mileage stated in this group is 48,000 miles, and the complaints describe failures both while starting the vehicle and while driving.

    Recall 26V248000Recall 26V5990002 related service bulletins

    What to check: Ask whether the DC-DC converter or the 48-volt charging system has been checked under the related recall campaigns, and check for any battery or hybrid warning messages at start-up. Ask the seller for records of hybrid system repairs and confirm that any recall work was completed.

    2 excerpts from owner complaints in NHTSA records

    “The DC/DC converter is failing on the vehicles regularly. This results in the vehicle losing power and shutting down while driving. I own this vehicle and while it hasn’t happened yet, I constantly fear that it will. With the common knowledge and frequency of this occurrence, Land Rover should fix as a recall to ensure the safety of all customers. Please push for this. Thank you.”

    NHTSA complaint #11709603, filed 2026-01

    “My 2020 Land Rover Defender 48V Mild Hybrid Electric Vehicle (MHEV) experienced a check engine light and hybrid electrical failure. Diagnostics by an authorized Jaguar Land Rover dealer confirmed code P0A1F-96 (Battery Energy Control Module / BECM internal component failure). This failure relates directly to an active, global safety recall issued by JLR (NHTSA Campaign 26V248 / JLR Recall D126) regarding DC-DC converter failures in MHEV vehicles. …”

    NHTSA complaint #11752326, filed 2026-07

Buying note. Ask the seller for records of lighting, windshield, and hybrid system repairs, and check whether any recall work on the DC-DC converter or the powertrain control module was completed. A pre-purchase inspection that confirms the daytime running lights, steering behavior, and hybrid warning lights work normally can help.

Example complaints

Exterior lighting: “The cone of light projected forward by the headlights is too narrow. When turning right or left from one dark road onto another dark road, one cannot determine if it is safe to turn. The light cone is blocked by the escutcheon around the headlight, which are set inward too deep.”

NHTSA complaint #11374036, filed 2020-11, 155 miles

Electrical system: “While driving my vehicle at high speeds on an interstate, the battery warning light activated. Before I was able to pull the vehicle over the air conditioner I'll probably begin to stop working. Following this, a series of multiple warning lights activated. The vehicle would not accelerate and I was forced to pull over. Following this, the vehicle would not activate whatsoever. All power was lost. I could not shift gear. The car required a tow to the local dealership.”

NHTSA complaint #11353875, filed 2020-09, 1,297 miles

Engine: “I am reporting a systemic failure of exhaust manifold retaining bolts on the 2020 Land Rover Defender (L663, P400 engine). While removing the engine skid plate, I discovered a fractured exhaust manifold bolt that had fallen down. The bolt head had separated, leaving the threaded portion in the cylinder head. There are I believe 12 manifold bolts securing the integrated exhaust manifold/turbocharger assembly, & multiple owners have documented similar failures, including cases with multiple broken bolts on one vehicle. …”

NHTSA complaint #11721177, filed 2026-02

Steering: “While driving on straight highway, the vehicle's lane keep assist feature which was turned off (the default position) activated automatically without driver input or warning and caused the steering wheel to turn and abruptly moved the vehicle from side to side. This required the driver to take corrective action to force the vehicle to remain straight. A considerable amount of force was required to override the automatic steering action.”
